Voice assistants like Siri and Google Assistant are always listening for verbal cues

While this always-on functionality can be useful, it also raises concerns about privacy and security. Users might want to disable virtual assistant apps and prevent other apps from accessing their microphone. On an iPhone, you can navigate to Settings, search for "Microphone" in the search bar, and then toggle off the relevant apps. On an Android phone, you can navigate to Settings, select "Google", tap "All Services", choose "Search, Assistant & Voice", select "Google Assistant", and then toggle off "Hey Google" and "Voice Match".

In addition to voice assistants, many other apps can access your phone's microphone. Social media apps like Snapchat and GPS tools like Google Maps might access your microphone to enable full functionality. It's important to consider which sites and applications are accessing your microphone, why they need access, and whether they are sharing your personal data.

While some people might find the convenience of voice assistants worth the trade-off in privacy, others might prefer to limit the data collected by their phones. One way to do this is by using a mobile security app to encrypt your connection and protect your device against threats.

Apps like Snapchat and Google Maps access your microphone for full functionality

It is important to note that it is legal for phones to listen to you if you accept the terms and conditions and give apps, systems, and software consent to access your microphone. However, it is not legal for spyware or other forms of phone takeover to listen or spy on you without your consent.

While these functionalities enhance the user experience, there are concerns about data privacy and security. Some apps may misuse permissions to record more data than intended, potentially for targeted advertising or eavesdropping on sensitive conversations. To address these concerns, users can take proactive steps such as disabling virtual assistants, reviewing and limiting application permissions, and keeping software up to date.

Additionally, users can physically cover their microphone with tape or purchase a special phone case to ensure privacy. However, it is essential to remember to remove any physical barriers before making a call or recording audio to avoid muffled sound quality.

Your phone data may be used to recommend ads and content

Your phone data can be used to recommend ads and content, and this is a common practice. Websites and apps collect and use your information in various ways, and this includes advertisers. When you browse the web, you may see pop-up requests asking for permission to track your activity. If you allow tracking, you will likely be shown targeted ads based on your browsing behaviour. For example, if you visit a website about fish tanks, you will likely see fish-related ads afterwards.

There are several types of data that can be used to recommend ads and content:

  • Location data: Your phone tracks your location through GPS, Wi-Fi signals, and IP address tracking. This data can be used to serve you geo-targeted ads.
  • Search and browsing history: The terms and phrases you search for online inform future search results and ad personalisation. The websites you visit and the pages you engage with help platforms refine content recommendations and targeted advertising.
  • Purchase history: Your online and in-store transactions linked to digital payment methods contribute to personalised shopping suggestions.
  • Physical interactions: Devices monitor how you interact with them, including touch patterns, screen time, and app usage, to improve user experience and personalise content.
  • Third-party tracking: When a website you visit allows another company to track you, third-party tracking occurs. This enables advertisers to show you targeted ads based on your interests and online activity across most websites you visit.

It is important to note that while your data may be used to recommend ads and content, your personal information is not sold to advertisers. Reputable advertisers do not link your data directly to personal identifiers such as your name or home address. Additionally, sensitive information such as health, race, religion, or sexual orientation is not used to tailor ads. You also have control over your data and can adjust your privacy settings to limit personalised ads and delete your activity data.

You can disable virtual assistants and review microphone permissions

If you are uncomfortable with the idea of your phone's microphone being accessed by law enforcement, you can take steps to secure your device by disabling virtual assistants and reviewing microphone permissions.

Disabling Virtual Assistants

Virtual assistants are voice-activated software programs that respond to your voice commands and perform tasks for you. These assistants often collect your voice data, which can be accessed by third parties, including law enforcement, with or without your knowledge.

  • Siri (iOS): Go to Settings > Siri & Search. Disable "Listen for Hey Siri" and "Press Side Button for Siri". You can also turn off Siri suggestions, which offer personalized recommendations based on your device usage.
  • Google Assistant (Android): Activate Google Assistant, usually by pressing and holding the home button. Select your profile icon, then go to 'Assistant Devices'. Choose the device you want to disable and switch off the Google Assistant slider.
  • Amazon Alexa: If you use a dedicated device like an Echo speaker, simply unplug the speaker to disable Alexa. To delete your voice data from Amazon, open the Alexa app, go to Settings, and scroll down to History. From here, you can delete your interactions with Alexa individually.

Reviewing Microphone Permissions

Reviewing and managing microphone permissions for your apps can help ensure that your microphone is not accessed without your consent. Here are some general steps for Android and iOS devices:

  • Android: Visit the gear icon in your Settings to access Security and Privacy settings. Under 'Privacy', you can find 'Microphone access' and toggle it off. You can also tap ''Permission manager'' to allow or deny microphone permissions for specific apps.
  • IOS: Go to Settings > Privacy & Security. Look for 'Microphone' under 'App permissions' and ensure that microphone access is allowed for the apps you want to use. You can then allow specific apps access to your microphone.

By disabling virtual assistants and carefully reviewing microphone permissions, you can enhance the security and privacy of your device, reducing the chances of unauthorized access to your microphone.

In the United States, it is illegal to monitor someone's phone without their knowledge or consent if they are 18 years old or older. This applies even if the phone belongs to your spouse. It is illegal to install software that records calls on someone else's phone without their permission. However, US law allows parents to monitor their children's cell phones and employers to monitor their employees' phones.

Many states allow someone to record a phone call or conversation as long as one person involved consents. This could be the person doing the recording. However, some states require that everyone involved in the conversation consents. This also depends on whether the person had a "reasonable expectation of privacy".

Spy apps are designed to go undetected on the target device, and the person being surveilled is typically unaware that their sensitive information is being collected without their consent. This can include emails, messaging app data, sites visited, texts, calls, and internet downloads.

While it may be legal to monitor someone's phone in certain circumstances, installing spying apps or software on someone's phone without their knowledge is illegal. This also applies to tracking people using a GPS device.

Frequently asked questions

Yes, law enforcement agencies such as the FBI can listen to private phone calls. They must request a wiretap order from a judge, who will only approve it if there is probable cause to believe it will help solve a serious crime or uncover criminal activity.

Examples of serious crimes include drug trafficking and money laundering. A judge will not approve a wiretap order for misdemeanors or less severe crimes such as driving without insurance or petty theft.

Wiretapping involves a secret connection to a telephone line, allowing agencies to monitor phone calls. There are also other methods such as "pen registers" and "trap and traces", which record phone numbers but not conversations.

If you suspect your phone is being tapped, you should contact a criminal defense attorney. They can help build a defense case and uphold your constitutional rights.
